-      The new <a href="/pkg/net/http/#ErrSchemeMismatch"><code>ErrSchemeMismatch</code></a> error is returned by <a href="/pkg/net/http/#Client"><code>Client</code></a> and <a href="/pkg/net/http/#Transport"><code>Transport</code></a> when the server responds to an HTTPS request with an HTTP response.
+    <p><!-- CL 472636 -->
+      The new <a href="/pkg/net/http#ResponseController.EnableFullDuplex"><code>ResponseController.EnableFullDuplex</code></a>
+      method allows server handlers to concurrently read from an HTTP/1
+      request body while writing the response. Normally, the HTTP/1 server
+      automatically consumes any remaining request body before starting to
+      write the response, to avoid deadlocking clients which attempt to
+      write a complete request before reading the response. The
+      <code>EnableFullDuplex</code> method disables this behavior.
